If I wish to construct a Voltaic Cell using Zinc-Zinc Ion and Silver-Silver Ion Half- Cells, which metal will serve as the Anode and which the Cathode? Justify your answer quantitatively 1. Data εAgAg+.redo + 0. 80 V = 2. Write a Cell Reaction for the above Cell. Write appropriate Half-Reactions 3. Draw a Cell Diagram for this Cell 4. Determine Ecell if 0.001 M ZnSO4 and 0.001 M Ag,SO4 are used as electrolytes. Identify the Oxidation and Reduction. i) First calculate Ecel ii) Then calculate the ionic strength I (Eq. 1) for the ZnSO4 and Ag SO4 electrolyte solutions ii) Use the Debye-Huckel equation (Eq. 10) to determine the activity coefficients yzn2- and iv) Finally determine Ecell using the Nernst Equation (Eqs. 7 and 9).
